Nuclear Power For Australia?


MIT technology review

The new owner of a plant in Michigan that was shut down in 2022 is now working to reopen it, as I reported in my latest story. If the restart is successful, the plant could operate for a total of 80 years. Others are seeing 20-year extensions to their reactors’ licenses. Extending the lifetime of existing nuclear plants could help cut emissions and is generally cheaper than building new ones. So just how long can we expect nuclear power plants to last?

 
Two main components determine a plant’s lifetime: the reactor pressure vessel and the containment structure, says Jacopo Buongiorno, a professor of nuclear engineering at MIT.
  • The reactor pressure vessel is the heart of a nuclear power plant, containing the reactor core as well as the associated cooling system. The structure must keep the reactor core at a high temperature and pressure without leaking.

  • The containment structure is a shell around the nuclear reactor. It is designed to be airtight and to keep any radioactive material contained in an emergency.

Both components are crucial to the safe operation of a nuclear power plant and are generally too expensive or too difficult to replace. So as regulators examine applications for extending plant lifetimes, they are the most concerned about the condition and lifespan of those components, Buongiorno says.

And that is why Torness is closing down as well as many other power stations.
Yep if, somehow, there is a way to repair/restore ancillary parts of Nuclear Power station it might make sense to do so.( I note that the writer also hedges his bet on the overall cost effectiveness of trying to repair various failing elements of a reactor. I think engineers would be very cautious about trying to restore 30 year old Nuclear Power stations. And if so at what final cost ?)

But that is not the case in the overall scheme of things. And it certainly should be postulated as the basis for a blue sky nuclear program in Australia.
 

For every negative reaction there a multiple positive reports.

In June 2019 the OECD’s International Energy Agency (IEA) published a report, Nuclear Power in a Clean Energy System, which concluded that a failure to invest in existing and new nuclear plants in advanced economies would make global efforts to transition to a cleaner energy system drastically harder and more costly.
In June 2022 the IEA report on Nuclear Power and Secure Energy Transitions concluded that nuclear energy can “help make the energy sector's journey away from unabated fossil fuels faster and more secure,” with nuclear being “well placed to help decarbonize electricity supply.” The report emphasizes the significant role nuclear plants can play in securing the global pathway to net zero carbon emissions.​

 

I guess the obvious question is Bas, where and when are the mega dams going to be built, to supply the long duration storage?
Snowy 2.0 is one, but several more will be required, yet no one is talking about it, I find that strange because everyone knows batteries can't do it and gas isn't much cleaner than coal.

So there is no point comparing nuclear with nuclear, people need to compare nuclear with something else that is clean and can supply long term grunt when it is required, otherwise it is just another hollow argument and a scam IMO.

People are quick to complain about the build time for nuclear and I do agree, but Snowy 2.0 has been going on for nearly 10 years and no other similar sized dam projects have been announced, so really isn't the nuclear argument similar to the renewables long duration argument?
People aren't stupid and both sides if politics have holes in both their stories, so credibilitity is a huge issue ATM.

Currently you have Dutton saying that nuclear wont cost a lot, but will supply the clean power required and the public dont believe the cost or the time frame, but they do believe the power output.
Labor is saying trust us we have this, but really a lot aren't sure, because there isn't any long term storage, there is a lot of issues with installing adequate renewable generation and there isn't many definitive answers on how much of anything renewable is required.
It is like a leap of faith project and I hope Labor get in to see it through, because the coal generators can't go on forever and people need to own the dream to get it done, or die on the cross trying, because it is a huge undertaking and kudos to them if they pull it off.
My guess is it will be a mop and bucket issue that will require a huge amount of money and pain to fix, time will tell.
First things first, we have to get Labor back in.

Yeah, because we’re heading down the socialist route we might as well continue towards the goal of highest taxed and most expensive electricity in the world.

"project cost estimates from 2020 with those given in 2024. Most projects costs were wildly underestimated...but we don't even know which projects the CSIRO included in the model because they haven't given us the data"​
 
Another wind farm cancelled under Labor government, state & federal.

 
Well if the majority want that, so be it, that's how democracies work.

One thing for sure it is better coming to a head sooner, rather than later, if Labor get in next election then serious decisions have to be made because if they aren't the system will fail.

Apparently from what I have read and been told renewables can do it, but I do know it will take a massive amount of renewables/ batteries and hydro.

Therefore next term it will have to be explained exactly where and how much, because the grid will be under a huge amount of strain and if failures start happening and there is no light at the end of the tunnel it will bring on an early election.

So I say bring on the transition, the sooner the better, if it works well it saves having to go nuclear, if it doesn't work nuclear will have to be used regardless of what people say.

It will at least make the decision obvious, rather than all this BS, double talk and smoke and mirrors, the longer the crap goes on the bigger the problem will become.
At the moment coal is carrying the day, the talk is gas will take over, but that isn't sustainable, so lets get on with separating the chaff from the hay.
IMO there will be a lot of Labor stalwarts leaving after the next election.
 
Australia is the only G20 country that maintains a nuclear ban.
Bowen can’t sustain any credible argument about costs until the Albanese government makes public its whole-of-system costings for its Reliable Renewables plan.
The opaque underwriting of secret contracts for renewable projects provides a bonanza in what’s described as crony capitalism. The government’s costings remain a mystery, and the Energy Minister maintains the fiction that the plan would cost $122bn.

 
Flying into Canberra and I noticed the size of a solar farm. Compare it to the house nearby.




I wonder how many this size is required to power Australia?

 
Riding around the ANU grounds, it is amazing.

The ANU has all the skills and technology to teach our brightest minds, as well as those from other countries.

Nuclear science is becoming an important field that crosses fields such as medical physics, mining, defence, security, policy as well as the classic field of physics. Our research-led teaching spans undergraduate and postgraduate levels and covers all aspects of nuclear science, including reactor science, nuclear fuel cycles and how to ensure policy debates on nuclear issues are informed by science and best practice.

 

Go figure, if the renewables plan falls on its butt, I wonder what plan B will be.
 

Post #491

Labor's energy flaws exposed
Amid the political fight over the Coalition's nuclear plan, the flaws in the federal government's own renewables-driven energy models - and the huge hidden costs to consumers- are being exposed.
The first Frontier Economics report did a service to the debate by unwinding an accounting trick. It revealed the real cost of the Integrated System Plan (ISP) - which has become de-facto policy for Labor - is around $600 billion. This figure towers over the discounted "present value" $121 billion figure touted by Energy Minister Chris Bowen.
But the second report - modelling the Coalition's nuclear policy - was more revealing. It showed that adopting nuclear would save more than $100 billion compared to a renewables-driven plan — sending critics diving into the details. What they end up surfacing may do more damage to Labor's plan than the Coalition's.
Bowen and his allies were quick to attack Frontier's modelling, accusing the report's authors of being silent on bill impacts for consumers.
This overlooks the fact that Frontier's analysis simply followed the ISP - the government's energy transition roadmap
- which also doesn't project power bill impacts.
The ISP can't project power bills because its modelling depends on a host of heroic assumptions, and arbitrary exclusions and inclusions. These range from speculative reliance on hydrogen and uncosted batteries, to a rigid commitment to government targets.
For example, some critics have claimed that the 90 per cent capacity factor assigned to nuclear -the amount of electricity a plant generates relative to its maximum potential - is unrealistic. With wind and solar providing half the energy, the argument goes, nuclear's remaining 38 per cent share of generation would not be able to operate in a continuous state.
If Frontier's model was built from the ground up to reflect reality, this critique might be valid. However, Frontier has anchored its analysis to the ISP, which supports implausibly low levels of spillage for wind and solar through a combination of acrobatic modelling and unrealistic assumptions.
The average capacity factors in the ISP model - 25 per cent for large-scale solar and 35 per cent for onshore wind-are extremely optimistic. Even today,
averages are closer to 20 per cent and 30 per cent. This will inevitably get worse as the share of wind and solar in the system more than triples, and the new generators cannibalise their own output.
The ISP makes this appear possible because it contains so much unrealistic, uncosted "spongy filling" to support a high penetration of weather-dependent generators- whose mismatch with demand is far worse than nuclear. The same fudge factors that make a 90 per cent weather-dependent system physically possible could easily allow a large nuclear fleet to run at 90 per cent.
The spongy filling in the ISP's Step Change scenario includes around 15 GW of ultra-flexible hydrogen electrolyser loads designed to perfectly soak up oversupply of solar - a pipe dream that's quickly unravelling as industry players pull out.
The plan also calls for a staggering 157 gigawatt-hours of home and electric vehicle batteries by 2050- that's more than 11 million new Tesla Powerwalls- with 90 per cent of these batteries controlled by grid operators to manage surplus wind and solar.
Under the government's plan, EV owners are increasingly expected to charge during the day and discharge in the evening - exactly the opposite of what they want. Surprisingly, none of these "consumer energy resources" are included as a cost in the ISP.
On top of that, the ISP assumes batteries can accurately predict the weather to optimise charging and discharging.
These crutches that keep the ISP from collapsing under its own weight are known to be unreasonable. Mr Bowen's own department commissioned a review - kept from the public for 11 months -that described this reliance on fully submissive consumer energy resources as "problematic" and a "limitation of the current ISP"
If the crutches were kicked away, the estimated costs of the renewables-only energy system would skyrocket, almost certainly exposing even greater benefits from nuclear.
The reality dawning on Australians is that we don't have any energy plan remotely close to giving us an honest picture of our future power prices.
Because Frontier has anchored its analysis to the ISP, it has made a transparent comparison that is almost certainly directionally correct: a system with nuclear will cost much less.
But because the baseline is so far out to sea, the dollar figures presented for either system are close to meaningless.
Australians are still none the wiser about whether or when prices will actually come down.
This uncertainty about eventual prices was laid bare during a Senate inquiry, when the market operator's CEO was asked whether following the ISP would lower power bills. His response? "I can't guarantee that, no."
The energy transition is too important and too costly to rely on models riddled with biases and fantastic assumptions. If Frontier's model has flaws, they're mostly inherited from the government's own fatally flawed plan.

I don't think it will be nuclear. I think they will build more coal stations first and take the flak from the Greens.
I doubt it, not because it wouldn't make sense because we do have a lot of coal, but because until it is proven emissions are not causing global warming reducing emissions is the main game.

There is no way new coal will go ahead, if it means global warming keeps increasing, that wouldn't make sense.

That's why I keep going back to the energy density of nuclear over renewables, at the moment the energy density of renewables is $hit, but in 50 years or 100 years time it may be brilliant, but we have to work with what we have.

Hopefully renewables can do it, but I doubt it, on the other hand nuclear can do it, but it is a finite resource, so eventually renewables have to do it.

It is just a case of being pragmatic and sensible, rather than tribal, it's a shame both sides are tribal rather than Australian IMO.

1. if people have to decide between keeping their beer cold or our tiny contribution to climate change, what would they pick do you reckon ?

2. The Greens are going to oppose anything to do with hydro or gas, the only viable options for firming renewables and won't vote nuclear either, so until they go nothing good will happen.

3. Nothing has been said about all the other contributions to GHG emissions, like agriculture etc.
 
I think they will pick nuclear, young people don't have the inherent fear of it and they know it has plenty of grunt, the worst outcome for young people would be the fear of actually not being able to get online and game.

They wouldn't even realise the problem with having no power, they have never really experienced it, so if it becomes commonplace they wont know how to cope and the backlash will be epic, much like the anti Vietnam protests IMO.

Interesting times. I must borrow @IFocus caravan if it goes pear shaped, I could put it on the sons block until everything is sorted.

On a side note, we just had a quick 5 minute blackout, so I quickly jumped on the scooter and went around the corner to the CBD, the power was still on, my guess is they have finished installing the new remote controlled meters in our sector and were testing it during a low demand period.

Pick off the low hanging fruit first, but people wont be happy if the low hanging fruit goes pear shaped.

I've actually attended meetings where it was said if the public has to have a few blackouts so be it, then when the blackouts start those same people start screaming that it isn't acceptable.

Everything changes when people actually have to face a bit of hardship, I don't think a lot of the East Coast elites have, so it will be interesting if that situation eventuates.

As I've said, I would be surprised in Albo and Chris hang about after the next election, hopefully they do.

I was reading today the Green vote has fallen with young voters, as I said they are connecting and discussing on social media, so some of the young will go with the renewable story others will go with the nuclear story.
What they wont go with is the Greens opposition to everything, it doesn't make sense and the young WONT go without power, they have never been in that situation and as I said it would get ugly quickly IMO.

Took our new van (2nd hand 1 year old) to Bremer Bay recently for the 1st trip you would enjoy it everything works very comfortable, Bremer was stunning.
